clarification regarding kernal upgrade

[Former Member]

Hi Experts,

In our production system (OS:AIX) we have database and central instance in host A and the dialog instance on host B.

As per my understanding I need to extract the kernal patch in

hostA : DVEVMGS00/exe and SYS/exe/run

hostB : D01/exe.

I have never done a kernal upgrade in this type of schenario. Kindly confirm if this process is right or anything else I need to do.

Thanks and Regards,

Hi,

Plzz don't do like that HOST -A & HOST- B.

your central instance is there in HOST-A. Then do like this.

1. Go to market place download the latest kernal.

2. Stop your Sap Application Central (HOST-A) & Dailog (HOST-B) aslo.

3. Take the backup of u r kernal dir that is RUN dir in HOST-A

backup means copy of run dir..

4. Then uncar the downloaded files in HOST-A.

5. Copy the all uncared files in RUN directory in HOST-A no need to copy HOST-B.

6. Than start u r central instance (HOST-A).

7. After complted successfully server up, then start u r Dailog instance (HOST-B).

8. Automatic kernal will be exfected. No need to copy kernal in Dailog.

Plzz do this i was already did my company. It working successfully.

Thanks & Regards,

Hi,

The kernel upgrade was successful.

I did in host A

DBEBMGS01/exe

SYS/exe/run - this is mounted to host B also

hostB

D02/exe

ASCS00/exe

Hi Amith,

Extract the Kernel patch to /sapmnt/<sid>/exe only on host A

On Node B please check whether /sapmnt/<sid>/exe in NFS mounted from host A,if that is the case you don't need to do the kernel upgrade on Host B,if its not an NFS just extract the kernel to /sapmnt/<sid>/exe to host B also.

Please make sure to take a backup of the kernel files before doing the upgrade.
